I'd also look at trust as being query independent and authority as query dependent. In my limited understanding it just seems to make sense.
"nodes may be pages, hosts, or sites..."
That's one of the problems I have when trying to read and understand a Google patent since over the years we've always talked about G being "page focused". It sometimes hard for me then to think in terms of the above quote and the following from the determining document freshness [appft1.uspto.gov] companion to the Historical Data patent:
A document may include an e-mail, a web site, a file, a combination of files, one or more files...
It kind of opens up a whole new can of worms where we can envision Google going past PageRank and assigining "DomainRank" and other site-wide attributes.
